Reactive blending of poly(l-lactide) and chemically-modified starch grafted with a maleic anhydride-methyl methacrylate copolymer

© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Blends of poly(l-lactide) (PLL) and chemically-modified native cassava starch (CMS) have been prepared by melt mixing and then fabricated into thin films for property testing. The CMS was prepared by copolymerizing maleic anhydride and methyl...
